A female screw part is provided, and a hole larger by a predetermined amount than a screw part screwed into the female screw part is provided in a vertical direction in a lateral part of the L-shaped connector. The L-shaped vertical portion is provided with an L-shaped inclined portion that abuts the Le-shaped inclined portion on the side surface of the lateral portion far from the hole, In a state where both inclined portions face each other, the L-shaped vertical surface and the Le-shaped vertical surface face each other, and the planar surface of the Le-shaped vertical portion is planar. The horizontal portion has a region protruding from the view, and each vertical frame is provided with a hole in the vertical direction from the upper end in at least the upper portion, and on the facing wall of each vertical frame facing each other A cutout portion is formed in the vertical direction from the upper end and is narrower than the hole. The protruding portion in the horizontal direction portion is received by any vertical frame or a part provided on the upper portion of the vertical frame. A mounting portion that can be mounted in the combined state. In the state of a connector assembly in which the threaded part through which the hole has been inserted is screwed into the female screw part, the connecting part is inserted into the notch part, and the hole of the vertical frame provided with the mounting part is provided. Inserting the L-shaped vertical portion and connecting the partition unit and the connection object by tightening the screw parts in a state where the L-shaped vertical portion is inserted into the hole of another vertical frame. Provided is a partition structure connecting structure.

In addition to the case of the partition unit, the connection target body may be, for example, a support used when two partition units are provided so as to intersect at right angles or the like. The hole that is larger by a predetermined amount includes a long hole that is long in a predetermined direction, and this long hole is preferable. Of course, any of the inclined portions includes a complete inclined plane, but if one is an inclined plane, the tangential plane in contact with the wavy surface is the same as the inclined plane even if the other is a wavy surface. Any angle of inclination may be used.
Furthermore, although it described as the structure which connects the upper part of a partition unit here, also in the case of the invention applied to a lower part, only the upper and lower sides of invention 1 are expressed reversely (for example, an upper part is expressed as a lower part). Well, it is described in the fourth invention.

In the second invention, the L-shaped inclined portion of the first invention is an inclined bottom portion of a groove provided in the L-shaped vertical direction portion, and the Le-shaped side engaging portion fits into the groove. is there.
According to a third aspect, the lateral portion of the first or second aspect is a shape that is cut out so that the vicinity of the connecting portion with the L-shaped longitudinal portion is narrow. The width of the width portion is configured to be equal to or less than the width of the notch.

  In the fourth invention, the terms “upper”, “upper part”, “upper end”, “upper part”, and “placement part” in the first or second invention can be replaced with “lower side”, “lower part”, “lower end”, “lower part”, and “pressing part”, respectively. The lower part of the partition unit is connected with the structure.

According to a fifth aspect of the present invention, there is provided a partition unit connection structure according to any one of the first to third aspects of the invention, and a lower portion connection structure of the partition unit. A lower-letter-shaped connecting tool, which is connected to the base portion and one base frame to be held by one of the vertical frames of the partition unit and the connection object. A lower re-shaped side engaging portion having a lower re-shaped side inclined portion inclined in a direction away from the upper side, and the inclined connector is connected to the base portion and the base portion to be held by the other vertical frame. And an engaging portion having an inclined portion that can face the lower recliner-side inclined portion and has the same inclination angle, while the inclined portion faces the lower reshaped-side inclined portion, It is configured to be able to engage with the lower letter-side engaging portion.
Of course, any inclined portion of the fifth invention includes a complete inclined plane, but if one is an inclined plane, the tangential plane in contact with the wavy surface is the same even if the other is a wavy surface. It may be the same inclination angle as the inclination plane.

In the first aspect of the invention, if a connector assembly in which two connectors are combined and screwed together with screw parts is inserted from above the partition unit, the lateral portion of the L-shaped connector is mounted on a vertical frame or the like. It is received and held by the mounting portion. Between the L-shaped vertical surface and the Le-shaped vertical surface in this state, the facing walls of the vertical frames of the partition unit and the connection object are located. In this state, if the screw member is screwed in from above, an elongated hole that is larger than the threaded part and is long in the direction in which the longitudinal surfaces approach each other, such as a so-called fool hole, and an L-shaped inclined surface The L-shaped connecting portion and the L-shaped connecting portion come closer to each other so that the respective longitudinal surfaces come closer to each other due to the inclined contact relationship between the portion and the L-shaped inclined portion. Therefore, both facing walls of the vertical frames can be sandwiched between the L-shaped vertical surface and the L-shaped vertical surface. Thereby, a partition unit and a connection target body can be attracted mutually, and can be connected firmly.
Moreover, since both facing walls of each vertical frame are clamped, the connector assembly is not easily pulled upward by friction. Therefore, as described in the fourth aspect, even when applied to the lower part of the partition unit, the connector assembly can be prevented from falling.

In the second invention, since the L-shaped engagement portion is fitted in the groove of the L-shaped vertical portion where the inclined bottom portion becomes the L-shaped inclined portion, when combined with the engagement relationship between the inclined portions, The assembly (temporary) assembly state of the assembly is stable, and smooth operations can be performed when each part of the connector assembly is inserted into both vertical frames.
In the third aspect of the invention, the partition unit is a horizontal part, and is narrowly cut out near the connecting part with the L-shaped vertical part, and the width of the thin part is equal to or less than the width of the cutout part. Even if the height of the object to be connected is different and the height is different, it is possible to insert the cut-out narrow part into the cut-out part of the facing wall of the higher vertical frame, so the mounting part is low If it is provided on the other vertical frame or a part provided on the upper frame, it is possible to connect differently.

In 4th invention, the lower part of a partition unit can be connected by making the same connector assembly same as 1st and 2nd invention upside down.
In the fifth aspect of the invention, as means for connecting the lower part of the partition unit, the lower letter-shaped inclined part of the lower letter-shaped engagement part of the lower letter-shaped connector held by one vertical frame and the other vertical letter The other vertical frame side is moved, for example, so as to be inserted from above so as to face the inclined portion of the engaging portion of the inclined connector held by the frame, thereby lowering the lower label of the lower connector. The engaging portion of the inclined connector can be engaged with the character side engaging portion. After this, the upper part of the partition unit is connected, and by tightening the upper screw parts, the two vertical frames holding the lower connecting parts, that is, the partition unit and the objects to be connected are attracted to each other, and the lower part Can follow the movement, and the connected state of the partition unit is stabilized by combining the upper part and the lower part.

  FIG. 1 is an exploded perspective view of an L-shaped connector 10, a L-shaped connector 20, and a screw component 30 used in the connection structure according to the present invention, and FIG. 2 shows three components of FIG. 1 from different directions. FIG. 3 is an exploded perspective view, FIG. 3 is a top view (a), a side view (b), and a bottom view (c) of the connector assembly 40 in which these three parts are temporarily assembled. FIG. It is sectional drawing for description of the motion between components at the time of combining components. The connector 10 is referred to as an L-shaped connector because the shape in side view looks generally L-shaped, and the connector 20 is referred to as a letter-shaped connector because the shape in side view looks generally L-shaped. Both connectors are metal castings or resin moldings.

  In the present application, the directional expressions such as vertical, vertical, and horizontal in each connector are directions in the usage state as the connector. Except for the latter part of the present specification, a structure for mainly connecting the upper parts of partition units 50 and 60 such as partitions will be described. Therefore, on that premise, for example, the upper side of FIG. 1 is the upper side of the coupler. The L-shaped connector 10 is composed of an L-shaped longitudinal portion (unless confused, it may be simply referred to as a longitudinal portion, and the same applies to other portions in the following description) 14 and the lateral portion 12. It is almost L-shaped. In the vertical direction portion, the vertical direction surface 14S is provided on the surface on the side where the horizontal direction portion is provided, on both the left and right sides of the narrow width portion 12H of the horizontal direction portion described below.

  The horizontal portion 12 has a narrow portion 12H formed narrower than its front portion in the vicinity of the connecting portion (intersection) with the vertical portion 14. This narrow width portion is a width that can be inserted through a notch F1K of the vertical frame F1 described later, and is necessary for connecting the partition units 50 ′ and 60 having a step shown in FIG. 9 described later, but there is no step. The connection between the partition units may not be narrow, and may be, for example, a wide width indicated by a two-dot chain line 12H ′ in FIG. In addition, a long hole 18 penetrating in a vertical direction is formed at a predetermined position in the lateral portion 12. The long hole is long in the extending direction of the lateral portion, and the screw component 30 (the male screw portion 30N) is set to be movable by a predetermined amount in the longitudinal direction of the long hole. The dimension in the short direction perpendicular to the longitudinal direction is substantially the same as the outer diameter of the male screw portion.

  The other L-shaped connector 20 has a longitudinal portion 24 and an engaging portion 26 that forms a tip portion of the L-shape, and the connecting portion 22 is connected therebetween. A female screw portion 24N opened in the upper end surface 24T of the vertical direction portion 24 is provided in the vertical direction, and the screw component 30 is screwed therein through the long hole 18. Thus, the temporarily assembled connector assembly 40 can be configured. However, in the plan view of this assembly (or the combined state of only the two parts 10 and 20), the lateral portion 12 protrudes beyond the upper end surface 24T. It is formed large so as to have a region 12S. The protruding region 12S is clearly shown as a hatched region in the bottom view (c) of FIG. In this region, when the connector assembly 40 is inserted (dropped) into the vertical frames F1 and F2 (FIG. 5) such as the partition units 50 and 60 described later, it is received by a predetermined mounting portion and is vertically moved. It becomes an engagement area | region which positions.

  The longitudinal portion 24 of the L-shaped connector 20 is provided with a longitudinal surface 24S on the side facing the engaging portion 26, and the engaging portion is on the side facing the longitudinal surface 24S. An inclined surface 26 </ b> S is provided as an example of an inclined portion that is inclined in a direction away from the vertical surface.

  On the other hand, in the longitudinal portion 14 of the L-shaped connector 10, the side surface far from the long hole 18, that is, the side surface opposite to the side where the lateral portion is provided (opposite to the longitudinal surface 14S). The L-side inclined surface 16S, which is an example of an L-shaped inclined portion that comes into contact with the inclined surface 26S, is provided on the side surface. Therefore, when these two inclined surfaces come into contact with each other, the vertical surfaces 14S and 24S are in a positional relationship in which they face each other. During this time, the facing walls F1H and F2H of both vertical frames F1 and F2 shown in FIG. Can be held together.

  Although not an essential requirement from the viewpoint of the first invention, the inclined surface 16S is formed as an inclined bottom surface of the groove 14M provided in the longitudinal portion 14, and the groove is connected to the L-shaped connector. The joint portion 26 is configured to be fitted. That is, the width δ of the engaging portion 26 is set to be not larger than the groove width Δ of the groove 14M. From the viewpoint of the first aspect of the invention, this groove is not provided, and only an inclined surface may be used.

  For this reason, when combined as the connector assembly 40, the backlash in the groove width direction of the grooves 14M of both connectors is small, and the insertion work into the vertical frame becomes smoother. Further, since the inclined surfaces also come into contact with each other, it is possible to prevent backlash in the direction orthogonal to the groove width direction. Further, the width of the connecting portion 22 of the letter-shaped connecting tool is set to be smaller than the width of the vertical portion 24, and is set to a width (predetermined width) equal to or smaller than the width dimension of notches F1K and F2K of the vertical frame described later. Further, in this example, the width δ of the engaging portion 26 is also set to be the same as the width of the connecting portion in order to facilitate manufacture.

  The hole 10K provided in the upper projecting portion of the vertical portion 14 of the L-shaped connector is used when, for example, disassembling after the connector assembly 40 is used for connecting the partition panel, an appropriate hook-shaped member is hooked in this hole. Provided for easy lifting.

  FIG. 5 is an exploded perspective view for explaining the configuration for connecting the upper portions of a pair of partition units 50, 60 having the same height using the above-described connector assembly 40, and FIG. 6 is a top view thereof, FIG. Is a longitudinal sectional view in a connected state, and FIG. 8 is a top view thereof. Aluminum facing frames F1 and F2 are provided on the facing side edges where the partition units face each other. In addition, the frame of the partition unit is formed by arranging the horizontal frame Y1 and the like on the upper end and the lower end. The vertical frame F1 of the partition unit 50 is formed with a notch F1K extending from the upper end to the lower end in the facing wall F1H facing the opposing vertical frame F2 facing in this example. Furthermore, in this example, a substantially chevron-shaped hole F1A wider than the width of the notch is formed on the rear side communicating with the notch from the upper end to the lower end.

  The vertical frame F2 of the partition unit 60 is the same, and in this example, a notch F2K extending from the upper end to the lower end is formed in the facing wall F2H facing the opposing vertical frame F1. Further, in this example, a substantially chevron-shaped hole F2A that is wider than the width of the notch is formed on the rear side that communicates with the notch.

  The connecting portions of the L-shaped connecting tool 20 of the connecting tool assembly 40 in the temporarily assembled state shown in FIG. 4B, in which the facing walls F1H and F2H of the pair of vertical frames are arranged close to each other. 22 is inserted into both notches F1K and F2K, while the L-shaped vertical portion 24 is inserted into the hole F1A of the vertical frame F1, while the L-shaped vertical portion 14 of the L-shaped connector 10 is inserted into the other. It is inserted through the hole F2A of the vertical frame F2. A region 12S which is a lower surface region of the horizontal portion 12 of the L-shaped connector and protrudes from the upper end surface 24T of the vertical portion 24 of the L-shaped connector is received by the upper end surface of the vertical frame F1 and connected. The assembly 40 can be placed. However, in this example, the decorative part 52 is provided on the upper end side of the vertical frame F1, and the actual placement part is a step part 52D at a predetermined position of the part 52 shown in FIG.

  Thus, in a state where each part of the connector assembly 40 is inserted into both vertical frames, the facing walls F1H and F2H of each vertical frame are sandwiched between the vertical surfaces 14S and 24S of each connector 10 and 20. In this state, it is easy to tighten the screw part 30 from above. When the screw part is tightened, the screw part 30 passes through the long hole 18 of the L-shaped connector 10 and is relatively movable in the longitudinal direction of the long hole. c) Approaching the state. That is, due to the contact relationship between the inclined surface 16S and the inclined surface 26S having the same inclination angle, the vertical direction surfaces 14S and 24S of the two couplers 10 and 20 approach each other. Thereby, both the vertical frames F1 and F2 are firmly connected, and the partition units 50 and 60 are connected. Thereafter, the lid part 58 which is another decorative part is mounted. As described above, the connection structure of the present invention is simple because it is sufficient to simply drop the temporarily assembled connector assembly 40 and tighten the screw parts from above. At the time of disassembly, the screw may be loosened and pulled up using the locking hole 10K or the like.

In addition, since the vertical frames F1 and F2 are the same, even if the right and left of the connector assembly 40 shown in FIG.
FIG. 9 is a longitudinal sectional view showing a state in which the partition units 50 ′ and 60 having different heights are connected to each other. In order to enable this connection, as described above, the width of the base portion 12H of the horizontal portion 12, that is, the width of the vicinity of the connection portion with the vertical direction portion, is shown in FIG. 5 of the vertical frame F2 (F1 ′). The width of the notch F2K (F1K), which is the same as that, is set to be equal to or smaller than that. Thereby, the coupler assembly 40 can be pushed down to the position of the vertical frame F1 ′ of the lower partition unit 50 ′. The insertion of the longitudinal portion 24 of the L-shaped connector 20 into the hole F1A ′ of the vertical frame F1 ′ is the same as in the case of FIG.

  FIG. 10 is a top view for explanation when the partition unit 50 is connected to the support column 70, and FIG. 11 is a top view of a state in which two partition units 50, 50 ″ are connected in an orthogonal state via the support column. As shown in the figure, the support column 70 has a square outer shape in cross section or upper surface (lower surface), and it can be considered that the aforementioned vertical frames are arranged at intervals of 90 degrees. Are faced to the vertical frame F1 of the partition unit 50, and are connected by the above-described connector assembly 40. One vertical frame F2 ′ of the four vertical frame elements of the column 70 as the connection target in this case. Has a facing wall F2H ′, a cutout portion F2K ′, and a wider hole F2A ′ in communication with the cutout portion F2A ′, similarly to the vertical frame F2 described above. The same applies to the other partition unit 50 ″. It is.

  FIG. 12 is an explanatory view showing that the same connector assembly 40 used in the upper connecting structure between the partition units 50 and 60 in FIG. 7 can be used in the lower connecting structure. It is simply inserted upside down of the vertical frames F1, F2 with the connector assembly 40 upside down, and in the case of FIG. 7, a pressing portion (corresponding to a portion called a placement portion (stepped portion) 52D). The state pressed against the step part 52D is the insertion end position. At this position, the screw component is screwed in and firmly connected. As a result, since the connector assembly 40 strongly holds the facing walls F1H and F2H of the vertical frame, it is prevented from falling due to friction. In this example, both the upper part and the lower part are connected by using the same connector assembly, but the upper part may be used by another appropriate connector. Reference numeral 54 is a foot of the partition unit.

  Furthermore, as the lower connection structure having the above-described upper connection structure, there are examples of other connection structures shown in FIGS. 13 and 14. 13 is schematically shown in FIG. 14 and a longitudinal sectional view at the position of the arrow NN in FIG. 14 is schematically shown in FIG. The lower letter-shaped connector 80 is connected to a vertical base 82 and a lower letter-side engaging part 86 that is connected to the lower part of the base and whose width is equal to or less than the width of the notch F2K of the vertical frame F2. Have. The lower L-shaped side engaging portion has a lower L-shaped side inclined portion 84 that is inclined in a direction away from the vertical frame F2 when the base portion or the mounting portion is mounted, and the cross-section of the connector 80 is L-shaped. It has become.

  The base portion 82 of the lower leg-shaped connector 80 is inserted into the hole F2A from the lower side of the vertical frame F2, and, for example, a hexagon socket head screw 100 is attached to the lateral female screw portion 82N provided in the base portion 82. Screw in through the notch F2K of the vertical frame F2. Accordingly, the tip of the screw presses the wall F2AH that defines the hole F2A of the vertical frame F2, and the base 82 of the lower letter-shaped connector 80 presses the inner surface of the facing wall F2H of the vertical frame F2. As a result, the lower leg-shaped connector 80 is held at an appropriate height position of the vertical frame by the frictional force. Further, the lower letter side engaging portion 86 protrudes to the outside as shown in FIG. 13 through the notch F2K.

  On the other hand, in the vertical frame F1 of the mating partition unit 50, the inclined connector 90 is held at an appropriate predetermined height position of the vertical frame F1 by the same structure and principle as the lower letter-shaped connector 80. . The inclined connector 90 includes a base portion 92 having an internal thread portion 92N, and an engaging portion 96 that is connected to the base portion and can face the lower leg-shaped inclined portion 84 and has an inclined portion 94 having the same inclination angle. Have.

  In order to connect the two partition units 50, 60 holding the two connecting tools 80, 90, as shown in FIG. 13, in this example, the partition unit 50 is positioned higher. The lower part of the partition unit is engaged and connected so that the engaging part 96 is hooked on the engaging part 86 of the other connector 80. Then, the upper connection using the connection tool assembly 40 described above is performed. In order to follow this upper connection, the lower connection part is inevitably connected by the action of the inclined portions 84 and 94 so that the facing walls of the vertical frames of both partition units are close to each other.
